B-decays and B- antiB mixing within a heavy-light chiral quark model

Jan O. Eeg

We describe a recently developed heavy-light chiral quark model and show how it can be used to calculate decay amplitudes for heavy mesons. In particular, we discuss B- antiB mixin…

Nonfactorizable contributions in anti-B0 -> Ds+ Ds- and anti-Bs0 -> D+ D- decays

J. O. Eeg, S. Fajfer, A. Hiorth

The decay amplitudes for anti-B0 -> Ds+ Ds- and anti-Bs0 -> D+ D- have no factorizable contributions. We suggest that dominant contributions to the decay amplitudes arise from two…

On the Short Distance Part of the QCD Anomaly Contribution to the b --> s eta' Amplitude

J. O. Eeg, K. Kumericki, I. Picek

In addressing the B --> eta' K puzzle, there has been a considerable hope in the literature to resolve it by the QCD anomaly contribution to the b --> s eta' amplitude. This contri…

The β-term for D^* --> D γwithin a heavy-light chiral quark model

A. Hiorth, J. O. Eeg

We present a calculation of the β-term for D^* --> D gamma within a heavy-light chiral quark model. Within the model, soft gluon effects in terms of the gluon condensate with lowes…

On the Colour Suppressed Decay Modes B^0 --> D_s^+ D_s^- and B_s^0 --> D^+ D^-

J. O. Eeg, S. Fajfer, A. Hiorth

We point out that the decay modes B^0 --> D_s^+ D_s^- and B_s^0 --> D^+ D^- have no factorized contribution. At quark level these dacays can only proceed through the annihilation m…

Non-factorizable effects in B-anti-B mixing

A. Hiorth, J. O. Eeg

We study the B-parameter (``bag factor'') for B-anti-B mixing within a recently developed heavy-light chiral quark model. Non-factorizable contributions in terms of gluon condensat…
